4 OVERVIEW
DESCRIPTION
The Meter Interface (MI) accepts inputs from external AC and DC power metering sensors such as: AC and DC voltage
and amps, AC kWatts, and DC battery capacity in amp hours and percent remaining. All with user definable high and
low alarms. The MI processes the information from these inputs and broadcasts it onto the CZone bus.
FEATURES
AC
•3 x AC voltage inputs (multi voltage)
•2 x AC current inputs
•Calculates true RMS power
DC
•3 x DC voltage inputs (multi voltage)
•2 x DC current inputs
•Calculates battery capacity as Ampere hours and percentage charge remaining
•Resolution for current metering down to 0.1A
Other
•IPX5 water ingress protection
•Outputs standard NMEA2000 power monitoring sentences
•Dimensions: H 100mm (3”29/32) x W156mm (6”3/32) x D 42mm (1”5/8) Weight: 281g

GUIDELINES
•Ensure the modules are installed vertically with the cables exiting downwards, this ensures IPX5 rating is
retained.
•All seals and cable glands must be fitted including blanking plugs inserted in any unused positions.
•Ensure all labels are fitted and correct
DC CONNECTIONS
All DC Connections are made on the 8Way connector.
•Connect each of the voltage inputs to the MI from battery banks. Ensure each input is fused at supply with a
1A fuse.
•Voltage Input 3 is a voltage meter only.
•Connect the current input from each shunt. Ensure care is taken when wiring shunt into heavy DC system to
make sure no negatives are left on the battery side of shunt.
•Connect DC negative to MI input 8. Used as a reference to ground.
•Connect an NMEA2000 drop cable from the MI to the NMEA2000 backbone.
•Ensure NMEA2000 network is properly terminated and connected to 12V power source.

Note: Current Input 1 is matched to Voltage Input 1, and Current Input 2 is matched to
Voltage Input 2. For correct metering these must be matched to same DC supply.

AC CONNECTIONS
AC connection and protection must be done in accordance with local standards. Do not work on the Meter
Interface or system if it is still connected to a power source. Only allow changes in your electrical system
tobe carried out by qualified electricians. All AC connections are made on the 6Way connector.
•Connect voltage inputs from AC voltage transformer to MI, inputs 2, 4 and 5.
•Connect current inputs from each current transformer to MI, inputs 1 and 3.
•Connect transformer common to input 6 from the Voltage Transformer.
•Ensure the potted end of the current transformer is facing the line direction. Part # CT-10-3

DIPSWITCH
•Using a small screwdriver, carefully set the dipswitch to required setting.
•The dipswitch number must be unique for all modules on the CZone network and must match the dipswitch
setting in the configuration to function correctly.
INITIAL POWER UP
1. Check all plugs are securely seated and connections are tight.
2. Power up the NMEA2000 network.
3. Check that the NMEA2000 Network LED lights up. It may also be flashing if other devices are present and
transmitting data.
4. Check that the Power indicator LED is green.
5. Check the circuit’s status LEDs for each individual circuit. Refer to LED codes to diagnose any faults which
need to be rectified.
6. Check the software version on the Meter Interface with the CZone Configuration Tool and update if
necessary.
7. Refer to the CZone Configuration Tool Instructions for details on how to configure and calibrate the Meter
Interface inputs.
8. Write configuration file to the Meter Interface and the rest of the CZone modules on the system.
9. Test all inputs for configured functionality.
Figure 3. Dipswitch Setting
The example shows a dipswitch number of 10000000 where 0 = Off and 1 = On.

CONNECTIONS/LED FLASH CODE LABEL
This label is located on the inside of the front lid of the unit, it shows the LED codes and electrical connections to the
unit:
MODULE IDENTIFICATION AND DIPSWITCH LABEL
These labels allow easy identification of each module whilst recording the dipswitch setting. These labels are to be
fitted to the cover and to the module (this prevents covers being swapped). To record the module type and dipswitch
settings use a permanent marker and strike through the applicable boxes (a strike through on a dipswitch box indicates
that switch is on).
